To all whom it may concern.-

Be it known that we, LEON J. HARLEY and CORNELIUS O. HARLEY, citizens ofthe United States of America, and residents of Springfield, in thecounty of Hampden and State of Massachusetts, have invented certain newand useful Improvements in Metal-Planing Machines, of which thefollowing is a full, clear, and exact description.

This invention relates to metal-planing machines of a very common typein which is comprised a movable tool-carrying head which has combinedtherewith mechanism including interchangeable parts operable forimparting to the tool-carrying head either a horizontal cross-feed or avertical feed, such planers as heretofore constructed and used beingcapable of planing at one time, according as the machine is set, eitheracross ahorizontal surface or acrossa vertical surface.

More especially the invention relates to improvements in aplaning-machine in which there are comprised a tool carrying head whichis movable horizontally and transversely and a tool -carrying head whichis movable vertically, and which machine includes a feed mechanismcooperative with both the movable heads, so that while one tool-carryinghead will have feed movements vertically the other head willsimultaneously have feed movements horizontally, whereby the machine iscapable of planing on the upper horizontal surface and on a verticalsurface or surfaces of a given'piece of work at the same time, and sothat the planing of pieces of work to be machined on sides at rightangles to each other may be accomplished twice as rapidly as possible inmachines having but one tool-carrying head and feed mechanism therefor.

Incidentally an aim of the invention is to impart to the machine thecapabilities for the right-angular feedings of its tool-carrying headsby the provision of simple equipments or attachments and without ageneral reo rgani zation of the planing-machine.

Another object is to provide the appliance comprising the head orsupport for the crossfeeding tool or tools of such construction that thepart which directly carries the tools may be temporarily swung into aposition which is free and clear of the head or heads, which latter inthe present improved machine are used for holding the tools for thevertical most convenient access to the heads for the other tools, whichis desirable in positioning or replacing the latter.

The invention consists, in a metal-planing machine, of the combination,with the carriage or movable work-table, a vertically-feedingtool-carrier, and a horizontally-feeding toolcarrier, of amechanism' incommon to and having motion transmitting connection with both thevertical and horizontally feeding tool-carriers and operable both tofeed the first vertically and the second horizontally; and theinvention, furthermore,consists in certain particular constructions andarrangement of parts, all substantially as hereinafter described, andset forth in the claims.

Proceeding now to describe our invention embodied in a planing-machineas we have constructed it, Figure 1 is an end elevation or face view ofthe standard and cross-slide ofa planing-machine having mounted inworking positions thereon the usual tool-carrying heads, and ourimproved tool-carryingframe, the work-table portion of the planer andduplicated pieces of work to be operated on being shown in verticalsection as taken transversely through the planer-bed, work-table, andwork. Fig. 2 is a perspective view of the tool-holding frame comprisinga part of the present invention. Fig. 8 is a side elevation as taken atright angles to Fig. 1. i is a vertical section as taken on line 4 4:,Fig. 1. Fig. 5 is a view of a ratchet and pawl comprised in themachine-tool-feeding devices and is shown, on a large scale, as combinedwith the screw-feed shaft for thetransversely-movabletool-carryingframe;and ig. 6 is a perspective viewof a convenient form of lifting-handle for the hinged portion of saidtool-frame.

In'the drawings, A is the bed of a metalplaning machine of substantiallengthwise extent and has formed thereon the longitudinally-extendingslideways for receiving the V-slides of the reciprocating work-table orcarriage B.

The belt-driven mechanism embodying the usual rack-and-pinionwork-table-propelling devices and the coacting work-table-reversingdevices are not shown, except such parts thereof as relate directly tothe actuating devices for the tool-feeding mechanism.

Fig.

About midway of the length of the bed A are the standards C (I, whichare supported on theside extension C of the bed. The top portion ofthese standards are united by the shelf-bar C Suitably guided in thesestandards O and extending transversely across the planer above thetraveling work table B thereof is the girder or large cross-bar D.Vertical screw-shafts cl, engaging the end portions of the cross-bar,are revolubly supported by each of the standards C and have bevelgearconnections with a horizontal crank-provided shaft d, by means of whichthe crossbar D and the tool-carrying heads mounted thereon are adjustedvertically. The crossbar Dhas an integral dovetail slide-rib a formedadjacent its upper edge, on which are mounted the saddles c of theswivel-heads E.

The tool-carrying hinged apron f, to which are clamped the cutting-toolsF, has suitable vertical adjustments relative to the saddle c and thescrews 9, operated by the hand-cranks g, position the heads so that thetools to be fed vertically will be initially at their proper heights.This same screw 9, which has a bevel-gear connection, as shown in Fig.4:, with the automatically-rotated spline-shaft G, is also employed as avertical feeding means for the tools F.

The foregoing is a brief reference to the planer parts relating to thevertically-fed cutting-tools F, as are common and well known, and by areference to Fig. 1 it is apparent that by employing a plurality ofcutting-tools, as here illustrated, beginning at the top edges, two ormore pieces of work,

such as the T-rails shown, may be simultaneously planed on their sideportions 00.

The parts comprisedin the cross-feed toolcarrying frame consist of twooppositely-located frames or brackets I I, each having slideways if forengagement with the slide-rib c of the cross-bar D. These side frames orbrackets are rigidly held in pro per relation to each other by theuniting top bar J, which is secured thereto by the screw bolts Athrust-plate K is next attached to one end of the cross-bar D by boltsIn it and supports in a perforation 70 therein the short screwthreadedcross-feed shaft L. This feed-shaft L has a screw engagement with oneside frame I of the transversely-movable tool-carrying frame, as shownin Fig. 1. A thrust-collar L is pinned to said shaft L and bears againstthe thrust-plate K. The front edge portions M of the side frames 1 arerecessed at m and receive therein the side pieces a of the pivotedcarrying tool bar or head N. This toolbar N, as seen best in Figs. 2 and3, is pivotally attached to the side frames by the pins 0, which passthrough the side pieces nthereof, the straight sides a of which bearagainst the straight back wall on of recess m, thereby maintaining thetool-bar N in. a working position, as shown in full lines in Fig. 3, or,as

-it also leaves the space in front of the vertically-feeding toolsunobstructed, so that such tools may be clamped in place or removed orinterchanged without difficulty.

A handle-bar P, (see Fig. 6,) having pins thereon, which are adapted toengage the holes 0 in the side pieces a of the tool-bar, forms aconvenient means for swinging the somewhat heavy fixtu re comprised inthe crossfeeding appliances from one position to another.

The toolbar N has provided thereon the tool-holding slotways q, (seeFigs. 1 and 2,) which receive in their proper initial adjustments thetool-posts Q, on which are adjusted and secured the tools R forhorizontal surface-planing. These slotways, which are approximately inpositions on thebar N over the work to be planed, are long enough inhorizontal extent for the proper range of lateral adjustments of thetools to be used.

At each reciprocation of the carriage the pinion it has a rotationalmovement, which motion is likewise given to the shaft G, which, throughthe usual bevel gear connections (shown in Fig. 4:) between shaft G andthe feed-screw g, gives the motion to the verticalfeedingtool-carryinghead E,(or pair thereof.) Now the same pinion gear-wheel itwhich actuatcs through the ordinary connections the feed-screw shaft 9by meshing into and rotating the pinion gear-wheel S simultaneouslyturns the short feed-screw shaft L, which by its engagement with thepart I, comprised in the carrier for the tools R R, horizontally feedsthe latter, it thus appearing that while the tools'F F are fed down thetools R R are fed crosswise as the planing on the sides and top-of thework progresses.

By having the bar N and side members n n pivotally mounted on the framemembers-I I 1. In a metal-planing machine, the combination with thecarriage and the stationary elevated cross-bar D,-of avertically-feeding tool-carrier supported intermediately on saidcross-bar and a structure comprising side frames or bracket's slidablyengaged with the end portions of said cross-bar,the transverselyarrangedtool-carrying bar or head N having at the ends thereof the angularmembers a n pivotally engaged with said bracket-frames,
